Ticket: Basic Authentication Issue in Kong 9.0.1 (Docker)

[CloudmarkGIT]

Problem Description:
After installing Kong 9.0.1 on a test server in Docker (version from Docker Hub: [link](https://hub.docker.com/r/kong/kong-gateway/tags?name=3.9.0.1)), basic authentication stopped working. The configuration is identical to the previous version, where authentication was functioning correctly.

There is a discrepancy in Kong versions across different platforms. Could you confirm if this is expected behavior?

• Docker Hub: 9.0.1
• GitHub: 9.0
• Latest officially supported version: 9.7 (needs verification)

Steps to Reproduce:

1. Installed Kong 9.0.1 from Docker Hub.
2. Configured basic authentication using the standard plugin.
3. The configuration is identical to the previous working version.
4. When accessing a resource through Kong, authentication is not requested—access is granted without credential verification.

Good evening, please tell me, will there be any comment?

​It seems there's a versioning discrepancy causing confusion. The Docker image tagged as 3.9.0.1 on Docker Hub corresponds to Kong Gateway version 3.9.0.1, not 9.0.1. This versioning aligns with Kong's semantic versioning, where 3.9.0.1 indicates a patch release following 3.9.0.​

Regarding the basic authentication issue:​

• Plugin Configuration: Ensure that the basic-auth plugin is correctly configured and associated with the intended service or route.​

• Consumer Credentials: Verify that a consumer with valid credentials exists and is linked to the basic-auth plugin.​

• Request Headers: Confirm that incoming requests include the appropriate Authorization header with the correct credentials.​

If all configurations are correct and the issue persists, consider checking the Kong logs for any error messages or anomalies that might provide further insight.​
For the most accurate information, refer to the official Kong documentation and Docker Hub tags to ensure consistency across platforms.
